- Soil electrical conductivity (EC) is an indirect measurement that has a very deep correlation with the physical and chemical properties of soil. Soil electrical conductivity is an indication of the availability of nutrients in the soil.
- The measurement of soil alkalinity and acidity is also highly dependent on soil electrical conductivity (EC).
- The greater concentration of salts in the soil leaves a detrimental effect on the absorption of nutrients.
- Very low electrical conductivity levels indicate low available nutrients, and very high EC levels indicate nutrient excess. Those with low EC are often found in sandy soils with low organic matter levels, while high EC levels are found in high organic soil content (more clay).
- Soil texture, salinity and moisture are the soil properties that most affect EC levels.
